[0023] A variable spoiler lighting device for a vehicle according to the present disclosure is described below with reference to the accompanying drawings. For the sake of clarity and convenience of description, the thickness of the wire, the size of the constituent elements, etc. may be shown in the drawings in an inaccurate scale. In addition, according to the present disclosure, the terms referring to the constituent elements hereinafter are defined by considering their respective functions and may vary according to the intention of the user or manager or the practice in the art. Therefore, these terms should be defined according to the context of this specification.

[0024] Figure 1 is a perspective view showing a variable spoiler lighting device for a vehicle according to a first embodiment of the present disclosure. Figure 21 is a perspective view showing a state in which the spoiler unit 100 of the variable spoiler lighting device for a vehicle according to the first embodiment of the present disclosure moves away from the forward direction of the vehicle. Figure 3 1 is a perspective view showing a tilted state of the second spoiler 120 of the variable spoiler lighting device for a vehicle according to the first embodiment of the present disclosure.

[0025] The variable spoiler lighting device for a vehicle according to the first embodiment of the present disclosure includes a spoiler unit 100 and a rear lamp 200 , which will be described in detail below.

[0026] The spoiler unit 100 is movably provided in the rear portion 10 of the vehicle. The spoiler unit 100 may be horizontally arranged toward a width direction of the vehicle.

[0027] The spoiler unit 100 moves along the front-rear direction of the vehicle according to the driving mode of the vehicle. Therefore, the spoiler unit 100 can extend toward a direction away from the forward direction of the vehicle, thereby having an elongated length in the direction away from the forward direction of the vehicle.

[0028] In addition, the spoiler unit 100 can be tilted in the height direction of the vehicle, that is, in the up and down direction of the vehicle according to the driving mode of the vehicle. Examples of the driving mode of the vehicle here may include a normal mode, a GT1 mode, a GT2 mode, and other modes. The spoiler unit 100 may include a first spoiler 110 and a second spoiler 120.

[0029] The rear portion 10 may refer to a rear roof, a rear pillar, a rear door, or a rear bumper of a vehicle. In this embodiment, the rear portion 10 of the vehicle is described, and the rear roof of the vehicle is taken as an implementation example. The rear portion 10 may include a roof body 11 and an actuator unit 12.

[0030] The spoiler unit 100 is slidably mounted on the roof body 11. The spoiler unit 100 can move in the front-rear direction of the vehicle in a state of being mounted on the roof body 11.

[0031] The actuator unit 12 may be provided on the roof body 11. The actuator unit 12 is connected to the spoiler unit 100 so as to move the spoiler unit 100 in a straight line. In other words, the actuator unit 12 may move the spoiler unit 100 in a straight line toward the front-rear direction.

[0032] In addition, the actuator unit 12 is connected to the spoiler unit 100 so that the tilt angle of the spoiler unit 100 can be changed. In other words, the actuator unit 12 can change the tilt angle of the spoiler unit 100 in the height direction (up and down direction) of the vehicle. The actuator unit 12 may include a first actuator unit 12a and a second actuator unit 12b.

[0033] The first spoiler 110 may be mounted on the roof body 11. The first spoiler 110 is connected to the actuator unit 12 and may be moved in the front-rear direction of the vehicle by the operation of the actuator unit 12. In other words, by the operation of the actuator unit 12, the first spoiler 110 mounted on the roof body 11 may be extended toward a direction away from the forward direction of the vehicle, thereby having an extended length in the direction away from the forward direction of the vehicle.

[0034] The second spoiler 120 may be mounted on the first spoiler 110. In other words, the second spoiler 120 and the first spoiler 110 may be stacked on top of each other. The second spoiler 120 may be rotatably coupled to the first spoiler 110. In other words, a side of the second spoiler 120 facing the forward direction of the vehicle and a side of the first spoiler 110 facing the forward direction of the vehicle may be coupled by a hinge shaft interposed therebetween.

[0035] The second spoiler 120 is connected to the actuator unit 12 and can be tilted in the height direction of the vehicle by operation of the actuator unit 12. In other words, the first spoiler 110 moves from the roof body 11 to the forward direction away from the vehicle, and then the second spoiler 120 can be tilted.

[0036] The first actuator unit 12a may be connected to the first spoiler 110. The first actuator unit 12a may move the first spoiler 110 in a straight line in the front-rear direction of the vehicle.

[0037] The second actuator unit 12b may be connected to the second spoiler 120. The second actuator unit 12b may change the tilt angle of the second spoiler 120 in the height direction (ie, the vertical direction) of the vehicle.

[0038] The rear lamp 200 may be provided in the spoiler unit 100. The rear lamp 200 may emit light in a direction opposite to the forward direction of the vehicle. In other words, a line or dot of light is emitted from an edge of the spoiler unit 100 that faces away from the forward direction of the vehicle.

[0039] The rear lamp 200 may be a high mounted stop lamp (HMSL) or a tail lamp. The rear lamp 200 may include light emitting diodes (LEDs). The rear lamp 200 may include a first lamp unit 210 and a second lamp unit 220.

[0040] The first lamp unit 210 may be provided in the first spoiler 110. The first lamp unit 210 may be positioned on a central portion of an edge of the first spoiler 110 facing a direction opposite to a forward direction of the vehicle, ie, rearward.

[0041] The second lamp unit 220 may be provided in the first spoiler 110. The second lamp unit 220 may be positioned on an edge of the first spoiler 110 facing in a direction opposite to a forward direction of the vehicle, and may be arranged at both sides of the first lamp unit 210, respectively.

[0042] The second lamp unit 220 may be exposed to the outside or not exposed to the outside according to the inclination angle of the second spoiler 120. In other words, when the inclination angle of the second spoiler 120 is 0 degrees (i.e., flat orientation), the second lamp unit 220 is blocked by the second spoiler 120, and thus the light emitted from the second lamp unit 220 cannot propagate to the outside.

[0043] In the case where the second spoiler 120 is tilted upward and thus the tilt angle thereof exceeds 0 degrees, light emitted from the second lamp unit 220 may propagate to the outside. Therefore, it is possible to check from the outside whether the second spoiler 120 operates.

[0044] Figure 4 1 is a block diagram showing a connection relationship between the control unit 300 of the variable spoiler lighting device for a vehicle according to the first embodiment of the present disclosure and each of its constituent elements.

[0045] refer to Figures 1 to 4 , the variable spoiler lighting device for a vehicle according to the first embodiment of the present disclosure may further include a control unit 300 .

[0046] The control unit 300 may control the operation of each of the first actuator unit 12 a and the second actuator unit 12 b .

[0047] The control unit 300 is electrically connected to the first actuator unit 12 a and may thus control the operation of the first actuator unit 12 a so that the first spoiler 110 moves in the front-rear direction of the vehicle.

[0048] The control unit 300 is electrically connected to the second actuator unit 12b. By controlling the operation of the second actuator unit 12b, the control unit 300 may change the tilt angle of the second spoiler 120 so that the second spoiler 120 tilts in the up-down direction.

[0049] The control unit 300 may control the operation of each of the first actuator unit 12a and the second actuator unit 12b according to the driving mode of the vehicle, which is automatically changed by a signal generated by a vehicle speed sensor of the vehicle. In addition, the control unit 300 may control the operation of each of the first actuator unit 12a and the second actuator unit 12b according to the driving mode of the vehicle selected by a manual operation of the occupant.

[0050] According to the first embodiment of the present disclosure, the operation process of the variable spoiler lighting device for a vehicle configured as above is described as follows.

[0051] refer to Figure 1 and Figure 4 , the driving mode of the vehicle is set to the normal mode, and the control unit 300 may control the operation of the first actuator unit 12a so that the first spoiler 110 does not extend in a direction opposite to the forward direction of the vehicle.

[0052] The second spoiler 120 moving together with the first spoiler 110 does not extend toward the direction opposite to the forward direction of the vehicle, and the control unit 300 may control the operation of the second actuator unit 12b so that the inclination angle of the second spoiler 120 is 0 degrees.

[0053] refer to Figure 2 and Figure 4 When the driving mode of the vehicle is set to the GT1 mode, the control unit 300 can control the operation of the first actuator unit 12a so that the first spoiler 110 extends in the direction opposite to the forward direction of the vehicle. At this time, the second spoiler 120 moving together with the first spoiler 110 moves away from the forward direction of the vehicle and extends in the direction opposite to the forward direction of the vehicle.

[0054] The control unit 300 may control the operation of the second actuator unit 12b so that the second spoiler 120 continues to maintain its tilt angle of 0 degrees. The movement of the first spoiler 110 may redirect the flow of the vortex formed behind the moving vehicle, allowing the vehicle to travel a greater distance. In addition, when the vehicle is traveling at a constant speed or high speed, the airflow is redirected more backward in a direction opposite to the forward direction of the vehicle than in the normal mode, thereby minimizing air resistance.

[0055] Reference Figure 3 and Figure 4 When the driving mode of the vehicle is set to the GT2 mode, the control unit 300 may control the operation of the second actuator unit 12 b so that the inclination angle of the second spoiler 120 is greater than approximately 0 degrees.

[0056] The control unit 300 can control the operation of the first actuator unit 12a so that the first spoiler 110 maintains its extended state in the direction away from the vehicle's forward direction after moving away from the vehicle's forward direction. The tilting operation of the second spoiler 120 can achieve the effect of generating downforce on the rear wheels of the vehicle when driving at high speed, thereby facilitating safe driving.

[0057] Figure 5 is a perspective view showing a variable spoiler lighting device for a vehicle according to a second embodiment of the present disclosure. Figure 61 is a perspective view showing a state in which the spoiler unit 100 and the side spoiler of the variable spoiler lighting device for a vehicle according to the second embodiment of the present disclosure are moved together in a forward direction away from the vehicle. Figure 7 1 is a perspective view showing a tilted state of a second spoiler 120 of the variable spoiler lighting device for a vehicle according to the second embodiment of the present disclosure.

[0058] refer to Figures 5 to 7 , the variable spoiler lighting device for a vehicle according to the second embodiment of the present disclosure may include a spoiler unit 100 , a rear lamp 200 , a control unit 300 , and a side spoiler 400 .

[0059] Only the side spoiler 400 of the variable spoiler lighting device for a vehicle according to another embodiment of the present invention is described, which is not included in the variable spoiler lighting device for a vehicle according to the first embodiment of the present invention.

[0060] The vehicle variable spoiler lighting device according to the second embodiment of the present disclosure has the same configuration as the vehicle variable spoiler lighting device according to the first embodiment of the present disclosure except for the side spoiler 400. Therefore, the description of other constituent elements can be applied to the second embodiment of the present disclosure.

[0061] The side spoiler 400 is movably disposed in the rear portion 10. The side spoilers 400 may be disposed at both sides of the rear portion 10, respectively. The side spoilers 400 may cooperate with the spoiler unit 100 and move together with the spoiler unit 100. In other words, the side spoiler 400, which cooperates with the spoiler unit 100, may move together with the spoiler unit 100 in the front-rear direction of the vehicle, thereby extending in a direction opposite to the forward direction of the vehicle.

[0062] The side spoilers 400 may be integrally formed with the first spoiler 110 such that they are respectively arranged at both sides of the spoiler unit 100 in a manner orthogonal to the first spoiler 110 .

[0063] The side spoiler 400 can redirect the air flowing in the direction away from the forward direction of the vehicle at the side of the vehicle. In other words, the side spoiler 400 can extend in a vertical position in the direction away from the forward direction of the vehicle. Therefore, the side spoiler 400 can maximize the aerodynamic performance by reducing the vortex and air resistance generated behind the vehicle when traveling.

[0064] In the variable spoiler lighting device for a vehicle according to the first and second embodiments of the present disclosure, the first spoiler 110 extending in a direction away from the forward direction of the vehicle according to the driving mode of the vehicle can minimize the air resistance generated behind the vehicle, thereby increasing the distance that the vehicle can travel. In addition, the second spoiler 120 changes its inclination angle in the up and down directions according to the driving mode of the vehicle, which can achieve the effect of generating downforce on the rear wheels of the vehicle when driving at high speed, thereby contributing to safe driving.

[0065] In the vehicle variable spoiler lighting device according to the first and second embodiments of the present disclosure, the second lamp unit 220 that is exposed or not exposed according to the tilt angle of the second spoiler 120 can provide operation information of the second spoiler 120 to a driver of another vehicle or a pedestrian.

[0066] The embodiments of the present disclosure are described in an exemplary manner only with reference to the accompanying drawings. It is obvious to those skilled in the art that various modifications may be made to the embodiments and various equivalent replacements thereof may be implemented.
